Tyson Fury’s co-promoter believes the venue for an undisputed clash between the WBC champion and unified belt holder Oleksandr Usyk is the only detail to be ironed out.
Bob Arum of Top Rank explained he anticipated a fight to go ahead, with the Middle East leading the way to host the clash.
"I'm very optimistic the fight is going to happen," Arum told Sky Sports.
"Both fighters have agreed to do the fight, the question is the site and we're talking to the Middle East because allegedly they're going to come up with the biggest purse ever in boxing history.
"And if they do, that's where the fight is going to go because money is money. If they don't, both fighters will agree to do the fight this spring at Wembley... but the fight will happen in my opinion, certainly within the first four months of the year.
"Fighters want to do the best for themselves because a fighter's career, no matter how great he is, is limited and they want to make as much money as possible.
"So that's the only issue - where will the fight be held? I would believe in the next week that will be determined and then we'll have an official announcement of the date and site for the fight - but that fight is happening."
Arum suggested that Wembley remained an option:.
"To do 95,000 people in Wembley, which we did for the Dillian Whyte fight... a lot of my friends who went to that fight said it was one of the greatest, if not their greatest, experience going to an athletic event," he added.
"Now, if it's a unification match between Tyson and Usyk, it'll be even more spectacular."
